Hello,
When an error occurs in the pseudo terminal displaying the "guix system
init" command output, the backtrace is not displayed correctly and the
keyboard cannot be used (arrows, tab, enter keys) to scroll down the
backtrace or dump it.
It can easily be reproduced by introducing an error in the "run-command"
function, this way:
--8<---------------cut here---------------start------------->8---
--- a/gnu/installer/utils.scm
+++ b/gnu/installer/utils.scm
@@ -184,6 +184,7 @@ (define (pause)
(((port _ ...) _ _)
(read-line port))))
+ (error 'fake)
(installer-log-line "running command ~s" command)
(define result (run-external-command-with-line-hooks
(list %display-line-hook) command
--8<---------------cut here---------------end--------------->8---
I suspect that we may need to run "newt-init" and "clear-screen" before
displaying the backtrace page.
Thanks,
Mathieu

Fixed with bf5e78d59fcb188d0bce02d93c93d06069178837.
